"Within hours of the surgery I was home the same day. I was experiencing hot flushes, confusion, and the first night I woke up in the morning and I was absolutely dripping with sweat," she said.
Ms Dyson found the aftercare galling, and said this was commonplace for women.
"We are discharged without hormones, without warning, and without support," she said.
"In my discharge notes it simply read, 'can try combined HRT [hormone replacement therapy] if she wishes', as if it were suggesting a glass of wine at the weekend."
This experience prompted her to start campaign group Surge Menopause, whose aim is to push the Department of Health and Social Care (DHSC) to revolutionise its offering.
The DHSC said it was taking action to combat deficiencies, including adding menopause advice to NHS health checks and bringing down gynecology waiting lists.
A spokesperson said: "It is unacceptable women are not receiving the proper care and support following surgical menopause and the Health Secretary has been clear that we inherited a broken NHS with too many women still subject to a system that doesn't listen to their experiences or understand their needs."
